PCIe 2.0 x 16 or 3.0 x 16 slot for 7970?

[wingclip]

Hi folks,
I have an Asrock Z 77 Extreme 4 motherboard. Among other things, it offers a PCI E2 .0 x 16 and PCI E3 .0 x 16 VGA slots.

Yesterday, I installed a 7970 graphics card and I placed it in the PCI E2 .0 x 16 slot. According to GPU Z, the graphic card reports that it supports PC IE by 16 V3 .0.

Does that mean that to get the full potential of the 7970 I should install it into the PC IE 3.0 x 16 slot?
Thank you,
Rich

You have a 3.0 slot, so put it in that. There's however no performance difference between installing on 2 or 3.

Usually you should put the GPU at the top PCIe slot.
But you can put it in whichever one you want,it doesn't matter.

There will hardly be a difference between 2.0 and 3.0. Anyhow, it is still a good idea to use the latest one. So install the card in PCIe 3.0 slot. No issues.
